Simplify per comment. Give upper security bound for small message set.

comment Is Information Loss in Crystalline Cipher a Good Approach to Anti-Cryptanalysis?
Granted, the bad telltale signs that I point are no proof of insecurity. That's why I did not make an answer, only a comment.

comment Is Information Loss in Crystalline Cipher a Good Approach to Anti-Cryptanalysis?
We have a policy stating, in Q&A style: " Do we accept questions asking for cryptanalysis of your cipher (hash function, ...) design? No, we do not. " $\;$ Also, the source code has bad telltale signs: no method stated, long key, "demonstration" of security limited to analysis of the statistical characteristics of keystream/cyphertext...

Add summary. No adversary (rather than just Alice) should be able to chose the message in the small set.

comment Key Check Value standard pratice for asymetric cryptography?
That indeed matches the question as asked. However there's a significant issue: it's big!

comment Algorithm for n-of-m keys with partial results
If " nobody is trusted to hold the complete key " in the question rules out that a trusted party (not among those holding a key share) holds the complete key, it's going to be critical to specify what the complete key is supposed to allow.
